Bio-Remediation-Managing Munching Microbes

The practice of using microbes to break down and clean up hazardous and unwanted chemicals has been used for many years. However, most people were first introduced to the practice of using oil digesting microorganisms in 1989, when television news broadcasts showed microbes being used in the cleanup of the Exxon Valdez spill, which deposited millions of gallons of oil along the shores of Prince William Sound, AK.

Nearly a decade after that environmental tragedy, specially developed microbes are being used today in automotive machine shops for parts cleaning and reducing waste disposal costs.

As this technology becomes more prevalent in the rebuilding industry, some shop owners may have questions regarding using microbes in their parts cleaning duties. According to the U.S. Environmental Protection Agency (EPA), bio-remediation is a treatment process that uses naturally occurring microorganisms or microbes to break down or degrade hazardous substances into less toxic or nontoxic substances.

Certain microorganisms can digest organic substances such as fuels, oils, grease or solvents that are hazardous to humans, animals and plants. Normally, these microbes break down the contaminants into harmless products, mainly carbon dioxide and water.

According to Greg Myers, sales manager for Steelabrator Cleaning Systems, San Antonio, TX, one reason for the interest in bio-remediation is driven by the continuing changes and stricter regulations governing solvents and aqueous cleaning practices. "Bio-remediation contributes to the industry

Open Loop/Closed Loop and Learning

Closed-loop control can be programmed to either add or subtract up to a certain percentage of fuel in order for the engine to reach the target air/fuel ratio.

Electronic Fuel Injection (EFI) is all the rage today and rightfully so. EFI has many advantages that allow us to dial in the fuel in a dramatically more precise fashion than was ever possible with a carburetor. One of the tools at our disposal is the closed loop algorithm where the target air/fuel ratio commanded in the ECU is compared to the actual air/fuel ratio read by the O2 sensor. If the two do not match, the ECU makes small changes by either adding or subtracting from the commanded fuel in the fuel table to equalize the two.
